To all whom it may concern. 7

Be it known that I; G[EORGE C; Arm vso v, acitizen of the United States;residing at Georgetown, in the county of NVilliamson and b tate ofTexas, have invented certain new and useful Improvements in \VaterproofCar-Doors; and I do hereby declare the following to be a full, clear,and exact description of the invention such as will enable othersskilled in the art to which it appertains to make and use the same.

The invention relates to improvements in freight car doors. p i j lheobject of the present invention is to improve the construction of vfreight ca r doors and to provide a simple; practical andefiicientfreight car door of. strong, durable and inexpensiveconstruction which will be water and air tight,\and which willbepractically indestructible case of a Wreck. I

A further object of the invention is to provide a freight car door ofthischaracter adapted. to be advantageously employed as a refrigeratorCar and capable also ofeffectually preventing a tramp or other intruderfrom closing the door from the interior and preventingan inspectionofthecar. t

Vith theseand other .objectsin, view; the

invention consists in the construction and novel combination ofpartshereinafter fully described, illustrated in the accompanyingdrawings and pointed out in the claims hereto appended; it beingunderstood that various changes in the form, proportion, size and minordetails of construction, within the scope of the claims, may be resortedto without departing .from the spirit .or. sacrificing 7 any oftheadvantages of the invention.

Inpractice about two revolutions of the screw w1ll be necessary tocarrythe door into and out of the door opening and the gear will beproportioned so that one-half of a revolution of the gear will rotatethe pinion a "s'uflic'i'ent distance to carry the door into or out ofthe'sald opening.

I This will enable the handle or lever of the gear to swing from ahorizontal position at one side of the. frame to a smnlar position atthe opposite side of the frame, but it may be arranged to swing to anyother desired position. The lever may besecured or sealed in any'desired position and if desired a suitable lock 27 may be employed forholding the door in the opening and preventing its outward movementtherefrom. The lock is preferably located at the bottom of the door andthe bolt of the lock may engagea keeper in the floor of the car. Anyother arrangement of lock may of course be employed.

The'door is equipped with a weather guard or strip 29 provided at theinner edges with an attaching portion 30 secured to the outer face ofthe door. The weather or guard strip 29 extends outwardly andprojects'over a roller 31 which is'mounted on the upper horizontal oneof the intermediate set of bars, as clearly shown in Figs. 3 and 4:. Theroller, which is mounted on the bar 8,'enables the weather guard orstrip, which is constructed of sheet metal or other suitable material,to slide inwardly and outwardly over theframe. Theslidable frame isprovided with'a bottom weather strip or guard constructed of sheet metalor other suitable material and secured intermediate of its ends to thebottom of the frame di-' rectly over the'lower slide 7 andextending inadvance and in rear of the said slidable frame so as to completely coverthe "guide when thedoor is in its open or-closed position. The lowerweather strip or guard is provided at its outer edge with a dependinglongitudinal flange 33 which fits'against the exterior of the lowerguide. The lower guide is protected from water and also the accumulationof dust and dirt and it' is preferably round, as shown, but any'otherform may of course' be employed as will be readily understood. The doorisreadily 0perated from the exterior to open and close it and also toslide it to and from the door opening and it. will be impossible for atramp or other intruder to enter the car and close the door from theinterior thereof and thereby conceal himself within the car.

The screw is made relatively large both for the provision of the coarsethread and also to providea construction which will be practicallyindestructible inevent of the wreck of a train." Also the easy operationof the door will remove all the objections urged against the ordinaryfreight car door and it will be unnecessary to employ tools ,7

or injure the'door to'open and close the same. The particularconstruction of the ing a door opening, and upper and lower guideslocated at the top and bottom ofthe door opening, of slides operating inthe said guides, a frame rigid with the slides, a car door movable intoand out of the door opening and provided with a nut, a screw mounted onthe sliding frame and engaging the nut for moving the door inwardly andoutwardly, a pinion fixed" to the screw, a gear wheel-mountedfor rotarymovement on the said frame and meshing with the pinion, and an operat ngarm or lever connected with the gear wheel and arranged to swing fromone'side of the frame tothe other-to move the door inwardly andoutwardly.

2. The combination with a car body having a door opening, of upper andlower guides, a slidable frame operating in the guides, a door mechanismmounted on'the frame and connected with the door for moving the sameinwardly and outwardly into and out of the opening of the car body, I

a horizontal'roller mounted on the frame and extending "along the sameabove the said mechanism, and a weather guard or str1p secured to thedoor and extending outwardly I therefrom and having its outer portionar- I ranged upon the said roller, said weather guard or strip beingmovable over the roller when the door is moved inwardly and outwardly."

In testimony whereof I affix my signature in presence of two witnesses.V
